What is it about?
A potassium (K)-doped lithium vanadate (Li3VO4) sample was synthesized by using the conventional solid-state reaction technique. X-ray diffraction results showed the polycrystalline behavior of potassium-doped lithium vanadate. It was also observed that the lithium (Li+) ion did not show its presence in the diffraction pattern, which indicates that potassium (K+) ions were well substituted in the interstitials and did not disturb the planes of the lithium vanadate matrix.

Why is it important?
The optical absorption study (ultraviolet (UV)–visible) showed that the materials were absorbed in the UV region only and remained transparent for the visible region. With an increase in the potassium-ion doping concentration, the absorbance peaks shifted slightly towards higher wavelengths, suggesting an enhancement of the particle size.
Perspectives
The ionic conductivity and transparency indicate the feasibility of designing transparent batteries with good UV-shielding properties.
